TELEPHONE-CALL REGISTR.

T 0 all whom t may concern Y Be it known that I, LAURENCE D. HannisoN, a citizen of the United States, and resident of Phoenix, in the county of Maricopa and State of Arizona, have invented certain new and useful Improvements in Telephone- Call Registers, of which the following is a specifica-tion.

The present invention has reference, generally, to telephonyT andthe invention relates more particularly to an improved registering apparatus therefor.

The invention has for its dominant object to provide a registering apparatus for telephones whereby a party calling a second part-y and not receiving an answer can register the number of his phone or the phone on which he desires to be called at 'the called station, thereby, providing a memorandum for the called party upon his return.

'It is also an object' of the invention to provide means for automatically operating the number registering means arranged at the called station, whereby, adesired number may be selected and printed on a suitable strip arranged adjacent thereto.

Avfurther object of the invention is to provide means 'for returning the registering means to normal posit-ion subsequent to a printing or registering operation.

Further` it is yet another object of the invention to provide means for automatically rendering the registering device operative after the bell at the called station has been rung a predetermined number of times.

'()ther independent objects are to provide features of construction of the apparatus which tend towardlthe attainment of the vabove aims irrespective of the relation in which they are used.

Other objects will be in part obviousjand in part pointed out hereinafter. y

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exeiiiplifiedin the construction hereinafter set forth and the scope of the appli cation of which will be indicated in the following claims. Y

Fig. 3 is a transverse section in detail through the type carrying wheel;

Fig. 4- is a. side elevation partly in section, showing the automatic circuit closing means whereby the registering apparatus is rendered active.

Fig. 5 is a diagrammatic view showing the arrangement of the electrical circuit for operating the various parts of the apparatus.

Fig. 6 is an edge view partly in section, of portion of the parts shown in Fig. 5.

Referring now more specifically to the drawings and in connection with which like reference characters will refer to corresponding parts throughout the several views, there is provided a casing .or housing designated in its entirety by the numeral 1, which housing serves as means for containing thevarious parts of the call registering apparatus and, of course, is located at the called station.

Rotatably mounted upon a stub shaft 2 which is in turn supported upon a bracket 3, is a type carrying wheel 4 including'inner and outer rims, which rims constitute the peripheries of disk like elements 5 and 6. Slidably arranged in suitable openings formed in the inner and outer rims are a plurality of type carrying rods or plungers 7, which plungers are normally held in their inoperative lpositions by means of coiledA tremity of the stub shaft 2 and has engage ment therewith, the said spring being supported upon the stub shaft by means of an angular bracket l0. A ratchet wheel 11 is keyed to a portion of the stub shaft 2 and serves as means for locking the type carrying wheel al in selected position.

Bearing brackets 12 are fixedly secured to a portion of the housing bottom and rotatably support therebetween a recording the said recording roller a rubber feeding roller 14C is also rotatably supported within suitable brackets, this roller being mounted upon a shaft 15 carrying upon one portion thereof the particular type selected upon the type carrying wheel.

A magnet 20 is supported Within the housing upon a bracket 21 and has arranged vadjacent its respective pole an armature plate 22 carried upon a rod 23 slidably mounted upon a substantially U-shaped bracket 24 and normally maintained in spaced relation from the said magnet pole by'fmeans of a coil spring 25. Pivotally carried upon the outer extremity of the rod 23 is a pawl 26, the rear extremity of which is offset as at 27 to provide an eflicient armature plate. l

Another magnet 28 is supported Within thel bracket 21 and has its poleso arranged as to attract the armature plate 27 of the pawl 26 when energized, while below the same a 'second armature plate 29 formed upon a pawl 30 which is pivotally supported in bearings 31 is arranged'. A contractile coil spring 32 having engagement with the pawls 26 and 30 serve as means for normally maintaining they lsame in engagement with the ratchet Wheel 11, thereby' locking the type carrying wheel. 34 are arranged directly beneath the magnet- 28, the latter being movable with relation to the former whereby when engaged by the armature plate 29 a permanent cgcuit will be closed through its respective magnet 28.

Pivotally supported upon a bracket 35 is a hammer 36, the lower extremity of which is arranged adjacent the pole of a magnet .37 and is adapted to be attracted thereby,-

at times, in order that the particular type which has been moved to selected positionsy by the carrying wheel 4 may be engaged and forced into contact with the carbon ribbon 19. A coil spring 38 having engagement with the bracket 35.`v and the lower portionof the hammer 36 serves as means for normally maintaining the same in spaced relation from the various type carrying plungers and the pole of the magnets 37.

.Circuit closing means comprlsing a substantially U-shaped element having weighted extremities is pivotally supported upon a bracket 39 secured to a portion of the housing bottomand serves for a purpose which will be subsequently apparent.

As means for automatically advancing or rotating the feeding Wheel 14 lthere 'ispro- L-shaped operating arm 42 pivotally mount- Contact plates 33 and ed on the shaft 15 and carrying thereon a pivotal pawl '43 engageable with the ratchet wheel 16. A contractile coiled spring 44 which is engaged with a portion of the arm 42 and the housing top serves as means for normally maintaining the former in its uppermost position. Upon the energizing of the magnet 40, it is evident that the plates 41` will be brought into engagement with the magnet pole and as a consequence theratchet wheel 16` together with feed Wheels 14 will Which means is arranged at the calllng station, there is provided a bracket 45 carrying a shaft 46 on which a ratchet Wheel 47 is mounted. A tripping element 48 having a plurality of beveled lugs 48 formed upon its peripheral surface is also mounted on the shaft 46 and is ada ted to rotate with the ratchetewheel 47. pring contact arms 49 are secured to a suitable base adjacent the bracket 45 and project upwardly into proximity of the tripping element 48, the adjacent contact arm being arranged in the path of travel of the beveled lugs 48" as shown to advantage in Fig. 4. Other spring contact arms 50 are carried by one of the contact arms 49 and are so arranged as to permit engagement of the beveled lugs 48 with the lowermost thereof. A magnet 51 is provided and serves to attra-ct the plate 52 carried upon the adjacent .end of a rod 53, which rod has secured' to itsvouter end a slidable pawl 54. To normally maintain the armature plate and pawl in retracted positions a coil spring 55 is engaged with an extremity of the rod 53 and with a bracket 56 'xedly supported upon the base of the circuit closing device.

To permit the turning of the shaft 15 by hand, a hand wheel 15 may be and preferabl is arranged upon the outer end thereof whlch projects beyond the housing 1.

Having reference now to the wiring of the various lmagnets of the registering apparatus, a indicates a source of, electrical inter osed therein and adapted to be engage by a cam 57 arranged upon the usual .number selecting dial 58 commonly used in conjunction with intercommuncating telephone systems, such dial or other kindred devlces fbeing located at the callin station. -Other conductors c are engage with the opposite poles of the source of energy a and wlth the Contact terminals of the magnets 37, certain of the said conductors having circuit closing means d interposed therewenas?.

in and operable by means of a lug 59 carried upon the periphery of the dial 58. From one of the conductors 0 abranch conductor e extends into engagement with one of the contact terminals' of the magnet 40 while the other contact terminal thereof is engaged by a conductor e which in turn extends into engagement with the lower portion of the hammer 36. The conductor e has connection with the' adjacent side of the V- shaped circuit closing element 39 while a conductor f' is engaged with the opposite side of the hammer 36 and extends from the same into engagement with one contact terminal of the magnet 28,'.the remaining terminal ef the said magnetbeing connectedadjacent the magnets 28 and are adapted to be closed upon movement of its armature 27 the same being connected with the magnet by means of branches y' and j', the former being connected with onerofV the conductors awhile the latter is connected with the conductor y". Conductors lo are extended from the conductors e 'and e into vengagement with the circuit closing means of' the'telephone and upon removal of the receiver from its supporting hook willserve to energize the magnet 40 for a be subsequently obvious. nger 60 is carri'ed upon one side of the, outer rim of the type carrying wheel 4 and is adapted to be 'engaged with the longer of the spring circuit closing arms h at times to discontinue the iiow of 4energy through the magnets 28.

The automatic circuit closing device shown in the Fig. 4 hasthe magnet 51 thereof engaged with a plurality of shunt wires Z extending from the bell ringing circuits m and has the spring arms 49 interposed in one of the conductors Z while the arms- 5() are interposedin one of the conductors of the bell ringing circuit m of .the telephone system. l y

In operation when the bell at the call vstation has been rung fora predetermined number of times one of the beveled lugs 48 carried by the tripping element 48 will engage the. adjacent spring arms 49 thereby closing the registering circuit and a second of the beveled lugs will engage one of the spring arms 50, thereby breaking the bell 'ringing'circuit Atthis time, the party callpur ose which willber of the calling phone upon the recording means arranged at the called station the cam 57 arranged upon the dial 58 will make and break a circuit through the conductors b according to the particular number turned upon the dial, thereby transmitting electrical impulses to the magnet 20. Each time a circuit is completed through the magnet l20, the armature plate 22 and the rod 23 are drawn into engagement therewith, thereby moving the type carrying wheel, 4 into a position whereat the corresponding number upon one of the type carrying plungers will be alined with the recording strip arranged over the feeding roller 14. When the circuit is broken during the turning of the cam the rod 23 will be returned to its normal position by means of the spring 25 engaged therewith. When the number of the calling station has been vobtained uponv the type carrying wheel4 the dial 58 is then returned to its normal or inoperative position, where- Y upon the lugs 59 carried thereby will 'engage the circuit closing means d thus closing a circuit through the magnets 37 and drawing the armature portion of the pivoted hammer36finto engagement therewith. Such 'movement 'will cause the hammer 36 to strike the alined type carrying plunger', impressing the characters arranged thereon upon the recording strip whereupon the said plunger will be immediately returned to its element which is connected to the conductor e, thus, for an instantl closing a circuit through the magnet 28whereupon the armatures 27 and 29 are' draw intoengagement therewith and the ratchet wheel 'il arrangedv upon the shaft 2 is disengaged. by the pawls 26 and 30 and the type carryingwheel permittedto return to its normal position-by means of the spring 9. As the armature 29 is drawn into engagement `with .the magnets. the contact membersl and 34 will be engaged and as a consequence apermanent circuit 'is established through the' magnet 28. thereby maintaining the pawls 26y and 30 out of engagement with the said ratohet wheel 1l until the type carrying wheel has returned to its normal or inoperative position whereat' it is ready to receive the 'next number to be registered thereby. il ust betere the type carrying wheel 4 is returned to its normal position a linger 30 carried thereby will engage the longer oi the spring circuit closing armsz, thereby breaking the` circuit through the magnets 28 and admiringg the pawls 26 and 30 to' rengage their respective ratchet wheels 11. Due to the engagement of the branch conductors 7c with the conductors e and e', it will be understood that the feeding roller 14 will be advanced one ste the sheet correspondingly advanced anc the rec'ord made while' the receiver is on the hook, thereby advancing the recording case and causing the number printed thereon to be spaced from the following number. Thus, the party at the called station upon his lreturn may readily read the various numbers of those stations to be called by him.

Although I have in the above description referred to the improved registering apparatus as being applicable to the intercommunicating type of telephone system, it will be evident to persons skilled in the art that the invention'may be used in conjunction with various other types of systems, such as conditions or preference may dictate.

As many changes could be made in the above construction and many apparently widely different embodiments of this invene tion could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying` drawings shall be interpreted as illustrative and not in a limiting sense. that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a mater of language might be said to fall therebetween.
